Orthogonality catastrophe and Kondo effect in graphene [PDF]

open access: yes, 2007
Anderson's orthogonality catastrophe in graphene, at energies close to the Dirac point, is analyzed. It is shown that, in clean systems, the orthogonality catastrophe is suppressed, due to the vanishing density of states at the Dirac point.
